A highly persuasive and emotional weight loss transformation scene, split image (before and after). On the left: an overweight, sad person looking tired, messy environment, dim lighting, feeling frustrated and hopeless. On the right: the same person fit, confident, smiling, athletic body, glowing skin, standing in a bright, clean, modern environment. Add subtle visual elements of urgency and scarcity, like a ticking clock, calendar pages flipping, or light rays symbolizing “limited time transformation”. Style should be ultra-realistic, cinematic lighting, high contrast, very detailed, 4K quality. Include space for text (clean composition) for a future headline like: "Lose up to 15kg in 30 days" Colors: left side darker tones (gray, blue), right side vibrant tones (gold, white, green). The image should trigger strong emotions: desire, urgency, hope, transformation. Professional marketing style, similar to high-converting fitness ads. --ar 1:1 --quality ultra --sharp focus --photorealistic
